3D printing
–
Objects can be of almost any shape or geometry and are produced using digital model data from a 3D model or another electronic data source such as an Additive Manufacturing File file. The term 3D printing originally referred to a process that deposits a binder material onto a bed with inkjet printer heads layer by layer. More recently, the term is being used in popular vernacular to encompass a variety of additive manufacturing techniques. United States and global technical standards use the term additive manufacturing for this broader sense. Early additive manufacturing equipment and materials were developed in the 1980s, but on July 16,1984 Alain Le Méhauté, Olivier de Witte and Jean Claude André filed their patent for the stereolithography process. It was three weeks before Chuck Hull filed his own patent for stereolithography, the application of French inventors were abandoned by the French General Electric Company and CILAS. The claimed reason was for lack of business perspective, Hull defined the process as a system for generating three-dimensional objects by creating a cross-sectional pattern of the object to be formed, but this had been already invented by Kodama. Hulls contribution is the design of the STL file format widely accepted by 3D printing software as well as the digital slicing, the term 3D printing originally referred to a process employing standard and custom inkjet print heads. The technology used by most 3D printers to date—especially hobbyist and consumer-oriented models—is fused deposition modeling, AM processes for metal sintering or melting usually went by their own individual names in the 1980s and 1990s. But AM-type sintering was beginning to challenge that assumption, by the mid 1990s, new techniques for material deposition were developed at Stanford and Carnegie Mellon University, including microcasting and sprayed materials. Sacrificial and support materials had become more common, enabling new object geometries. The umbrella term additive manufacturing gained wider currency in the decade of the 2000s, as the various additive processes matured, it became clear that soon metal removal would no longer be the only metalworking process done under that type of control. It was during this decade that the term subtractive manufacturing appeared as a retronym for the family of machining processes with metal removal as their common theme. The term subtractive has not replaced the term machining, instead complementing it when a term that covers any removal method is needed, both terms reflect the simple fact that the technologies all share the common theme of sequential-layer material addition/joining throughout a 3D work envelope under automated control. The 2010s were the first decade in which metal end use parts such as engine brackets, agile tooling uses a cost effective and high quality method to quickly respond to customer and market needs. It can be used in hydro-forming, stamping, injection molding, as technology matured, several authors had begun to speculate that 3D printing could aid in sustainable development in the developing world. 3D printable models may be created with a computer-aided design package, via a 3D scanner, or by a digital camera. 3D printed models created with CAD result in reduced errors and can be corrected before printing, allowing verification in the design of the object before it is printed, the manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting

–
3D Ultra Lionel Traintown is a 3rd person railroading game by Sierra Entertainment. It consists of train layouts, some of which the player can edit, Some of the locomotives include, Union Pacific EMD SW1500 switcher, an Atchison, Topeka and Santa Fe Railway F3A diesel locomotive, a generic 2-8-0 steam locomotive, and a 1950s passenger railcar. 3D Ultra Lionel Traintown Deluxe succeeded this game, There are six difficulties, known as job rosters. A 12th job is unlocked after completing the previous 11, most jobs involve the basic concept of picking up and delivering loads via different freight and passenger cars. Other jobs involve moving numbered freight cars to make valid addition, subtraction, multiplication, There are memory-matching, pick-up sticks, hangman, Tower of Hanoi, and anagram scramble jobs with set time limits. The game has seven different play environments including a desert, the arctic, a room. If the job has a limit, it will have a number of minutes in parentheses at the end. In both versions, this job bin is for begineers, tutorial, The Basics Just as it sounds, a guided tutorial explaining how to drive a locomotive, switch tracks, and couple cars together. Tutorial, Loads and Deliveries A second walkthrough mission, detailing how to refuel, pick up loads, tutorial, Signals The third guided mission, which teaches players how to change signal lights and place flags to stop or reverse trains without touching them. Tutorial, Special Track This fourth walkthrough tutorial teaches the player how to use a turntable, Bascule bridge, and this tutorial has a time limit. Train Park, Cactus Valley A free play park based in the desert, Train Park, Backyard A large free play park based in a backyard. Train Park, Living Room A free play park based in a living room, Train Park, Oak Valley An elaborate practice park, complete with twin Bascule bridges and a coal pier, the latter of which does not appear anywhere else. Build Park, Cactus Valley A custom-build park based in the desert, build Park, North Pole A custom-build park in the snowy Arctic Circle. Build Park, Oak Valley A custom-build park in the green Oak Valley, burger Time A simple first job, in which players load a refrigerator car with hamburgers and deliver it to the furniture factory. Santas Helper A slight bit more complicated, but quite straightforward still, involving delivering reindeer and Santas sleigh to Santas workshop. Fish to Fry Less simple than the past two, this job has players utilize a turntable to load up with fish and heating oil to deliver to the club for a fish fry. Think, Think, Think The first job not to involve train driving at all, tee Time The objective is to deliver golf balls to the mini golf course prior to a visit by the queen, but an underfueled locomotive and a drawbridge create obstacles. What a Mess In a small but somewhat complex layout, the objective is to deliver RC cars, the job is to sort the cars down the right line

5 (Murder by Numbers)
–
5 is the eleventh mixtape by American rapper 50 Cent. The album was set to be his studio album, a follow up to his 2009 studio album. However,50 Cent decided to release it as a mixtape, while recording 5,50 Cent listened to a mix of music performed by his favourite artists, including rappers Tupac Shakur and The Notorious B. I. G. In an interview with the Detroit Free Press,50 Cent explained these actions, stating and it creates a level to me, within myself, of how good the record has to be before Im ready to launch it. In the same interview, he described the album as a new sound for him and felt that it was more soulful. 50 Cent confirmed the title,5 in an interview with the radio station Hot 107.9 Philly on June 13,2012

5-HT2C receptor
–
The 5-HT2C receptor is a subtype of 5-HT receptor that binds the endogenous neurotransmitter serotonin. It is a G protein-coupled receptor that is coupled to Gq/G11, HTR2C denotes the human gene encoding for the receptor, that in humans is located at the X chromosome. As males have one copy of the gene and in one of the two copies of the gene is repressed, polymorphisms at this receptor can affect the two sexes to differing extent. At the cell surface the receptor exists as a homodimer, 5-HT2C receptors are widely distributed across the periphery and brain in humans. The 5-HT2C receptor is one of the binding sites for serotonin. Activation of this receptor by serotonin inhibits dopamine and norepinephrine release in areas of the brain. 5-HT2C receptors are claimed to significantly regulate mood, anxiety, feeding, 5-HT2C receptors regulate dopamine release in the striatum, prefrontal cortex, nucleus accumbens, hippocampus, hypothalamus, and amygdala, among others. Research indicates that some victims have an abnormally high number of 5-HT2C receptors in the prefrontal cortex. There is some mixed evidence that agomelatine, a 5-HT2C antagonist, is an effective antidepressant, antagonism of 5-HT2C receptors by agomelatine results in an increase of dopamine and norepinephrine activity in the frontal cortex. Many atypical antipsychotics block 5-HT2C receptors, but their use is limited by multiple undesirable actions on various neurotransmitters and receptors. Fluoxetine acts as a direct 5-HT2C antagonist in addition to inhibiting serotonin reuptake, however, an overactivity of 5-HT2C receptors may contribute to depressive and anxiety symptoms in a certain population of patients. Activation of 5-HT2C by serotonin is responsible for many of the side effects of SSRI and SNRI medications, such as sertraline, paroxetine, venlafaxine. Some of the anxiety caused by SSRIs is due to excessive signalling at 5-HT2C. Over a period of 1–2 weeks, the receptor begins to downregulate, along with the downregulation of 5-HT2A, 5-HT1A and this downregulation parallels the onset of the clinical benefits of SSRIs. 5-HT2C receptors exhibit constitutive activity in vivo, and may retain the ability to influence neurotransmission in the absence of ligand occupancy, thus, 5-HT2C receptors do not require binding by a ligand in order to exhibit influence on neurotransmission. Inverse agonists may be required to fully extinguish 5-HT2C constitutive activity, 5-HT2C receptors mediate the release and increase of extracellular dopamine in response to many drugs, including caffeine, nicotine, amphetamine, morphine, cocaine, and others. 5-HT2C antagonism increases dopamine release in response to reinforcing drugs, feeding, social interaction, and sexual activity all release dopamine subject to inhibition of 5-HT2C. Increased 5-HT2C expression reduces dopamine release in both the presence and absence of stimuli, conditions that increase cytokine levels in the human body may have potential to raise 5-HT2C gene expression in the brain

8th Fighter Wing
–
The United States Air Force 8th Fighter Wing is the host unit at Kunsan Air Base, Republic of Korea and is assigned to Seventh Air Force. Seventh Air Force falls under Pacific Air Forces, the Wings 8th Operations Group is the successor of the 8th Pursuit Group, one of the 15 original combat air groups formed by the Army before World War II. Established in Japan after World War II in 1948, the wing flew missions throughout the Korean War. Redesignated the 8th Tactical Fighter Wing in 1958, it remained in Japan until 1964, after a year in California, it moved to Southeast Asia, where its F-4 Phantom II crews earned the nicknames MiG killers and bridge busters. In 1974 the wing relocated to Kunsan Air Base, South Korea, for additional history and lineage, see 8th Operations Group Established in August 1948 in Japan, the wing provided air defense to the islands. On 20 January 1951, the wing gained its new designation as the 8th Fighter Bomber Wing, on 25 June 1950, North Korea invaded South Korea, starting a war that would last three years. As the Korean War began, the 347th Fighter Group was assigned to the 8th to fly combat missions, the wing provided air cover for the evacuation of Americans from Korea on 26 June, the day after the invasion. The first aerial victory of the Korean War went to 1Lt William G. Hudson, of the 68th Fighter Squadron, later the same day, 35th Fighter-Bomber Squadron F-80s scored the Air Forces first confirmed kills from jet aircraft. In August, the wing briefly reverted to the F-51 Mustang, returning to the F-80 in December 1950, the 8th Fighter Wing is known for the heroic actions of its members, including Major Charles J. S. During the next three years, the 8th flew more than 60,000 sorties while operating from bases in both Korea and Japan, the wing participated in 10 campaigns and earned three unit citations. The wing finished the war flying the F-86 Sabre beginning in 1953 and became responsible for air defense over South Korea until relocated to Itazuke Air Base, Japan in October 1954. During the war in Korea, the 8th shot down 18 enemy aircraft, with the end of the Korean War, the wing was assigned to Itazuke AB, Japan for the next ten years. On 1 October 1957, the 8th Fighter-Bomber Group inactivated, with the flying squadrons assigned directly to the wing. Less than a later, on 1 July 1958, the Air Force redesignated the wing as the 8th Tactical Fighter Wing. On 18 June 1964, the wing moved without personnel or equipment to George AFB, California, at Ubon, the 8th TFW carried out its wartime mission as it led the way for other tactical Air Force fighter units during the Vietnam War. The 25th Tactical Fighter Squadron replaced the unit as the fourth F-4D fighter-bomber squadron at Ubon, the wing carried out a number of roles during combat. By the end of 1966, aircrews assigned to the 8th TFW flew nearly 14,000 combat missions into Vietnam, one of the squadrons assigned to wing, the 555th Tactical Fighter Squadron, became known as the Ace squadron of the conflict. In May 1968, the wing was the first to use laser-guided bombs in combat, in October 1968, the wing picked up a Fast FAC assignment, under the call sign Wolf

10 Gigabit Ethernet
–
10 Gigabit Ethernet is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE802. 3ae-2002 standard, half duplex operation and repeater hubs do not exist in 10GbE. Like previous versions of Ethernet, 10GbE can use either copper or fiber cabling, however, because of its bandwidth requirements, higher-grade copper cables are required, category 6a or Class F/Category 7 cables for lengths up to 100 meters. The 10 Gigabit Ethernet standard encompasses a number of different physical layer standards, a networking device, such as a switch or a network interface controller may have different PHY types through pluggable PHY modules, such as those based on SFP+. At the time that the 10 Gigabit Ethernet standard was developed, the WAN PHY encapsulates Ethernet packets in SONET OC-192c frames and operates at a slightly slower data-rate than the local area network PHY. Over the years the Institute of Electrical and Electronics Engineers 802.3 working group has published several standards relating to 10GbE, to implement different 10GbE physical layer standards, many interfaces consist of a standard socket into which different PHY modules may be plugged. Physical layer modules are not specified in a standards body. Relevant MSAs for 10GbE include XENPAK, XFP and SFP+, when choosing a PHY module, a designer considers cost, reach, media type, power consumption, and size. A single point-to-point link can have different MSA pluggable formats on either end as long as the 10GbE optical or copper port type inside the pluggable is identical, XENPAK was the first MSA for 10GE and had the largest form factor. X2 and XPAK were later competing standards with smaller form factors, X2 and XPAK have not been as successful in the market as XENPAK. XFP came after X2 and XPAK and it is also smaller, the newest module standard is the enhanced small form-factor pluggable transceiver, generally called SFP+. Based on the small form-factor pluggable transceiver and developed by the ANSI T11 fibre channel group, it is smaller still, SFP+ has become the most popular socket on 10GE systems. SFP+ modules do only optical to electrical conversion, no clock and data recovery, SFP+ modules share a common physical form factor with legacy SFP modules, allowing higher port density than XFP and the re-use of existing designs for 24 or 48 ports in a 19 rack width blade. Optical modules are connected to a host by either a XAUI, XENPAK, X2, and XPAK modules use XAUI to connect to their hosts. XAUI uses a data channel and is specified in IEEE802.3 Clause 48. XFP modules use a XFI interface and SFP+ modules use an SFI interface, XFI and SFI use a single lane data channel and the 64b/66b encoding specified in IEEE802.3 Clause 49. SFP+ modules can further be grouped into two types of host interfaces, linear or limiting, limiting modules are preferred except when using old fiber infrastructure which requires the use of the linear interface provided by 10GBASE-LRM modules. There are two classifications for optical fiber, single-mode and multi-mode, in SMF light follows a single path through the fiber while in MMF it takes multiple paths resulting in differential mode delay

13.2mm TuF
–
The Mauser 13. 2mm TuF, was a major step in the development of anti-tank cartridges, being the first cartridge designed for the sole purpose of destroying armored targets. The cartridge was used in the Mauser 1918 T-Gewehr rifle and its use was also planned in a new machine gun scheduled for deployment in 1919, the MG18 TuF. The 13.2 mm Tuf was designed to counter early British tanks which made their appearance during late World War I. Since a tanks path was difficult to determine prior to its deployment near the front, light artillery pieces pressed into service as anti-tank guns were very effective, but cumbersome and difficult to bring into action quickly enough. Thus, another means of combating these early armored vehicles needed to be found. The development of the.50 BMG round is sometimes confused with the German 13.2 mm TuF, however, the development of the U. S.50 caliber round was started before this later German project was completed or even known to the Allied countries. When word of the German anti-tank round spread, there was debate as to whether it should be copied and used as a base for the new machine gun cartridge. The rounds dimensions and ballistic traits are totally different, the 13.2 Tuf utilized a 92mm long semi-rimmed case featuring a shallow bottle-neck. It was developed by the Polte ammunition factory in Magdeburg, Germany, list of rifle cartridges 13 mm caliber http, //www. quarryhs. co. uk/ATRart. htm

15th World Scout Jamboree (cancelled)
–
The 15th World Scout Jamboree was scheduled to be held 15–23 July 1979 and was to be hosted by Iran at Nishapur, but was cancelled due to the Iranian Revolution. The 15th World Jamboree was to be held at the 10 square kilometre Omar Khayyám Scout Park, near the Afghan, the Second Asia-Pacific Jamboree was held at the site in preparation, in the summer of 1977. However, the events of the Islamic Revolution caused the 15th World Jamboree to be cancelled near the end of 1978. However, a number of items had already been made for the event, the demand for which. The few items of memorabilia in existence are of value to collectors when they, albeit rarely. The next Jamboree, hosted by Canada in 1983, was named The Spirit Lives On to show how Scoutings spirit of brotherhood could overcome the setback of cancelling the 1979 Jamboree.

19th Weapons Squadron
–
The 19th Weapons Squadron is a non-flying United States Air Force unit, assigned to the USAF Weapons School at Nellis AFB, Nevada. The squadron was first activated as the 19th Observation Squadron in March 1942, the 19th originally flew antisubmarine missions during World War II, then moved to China in 1944 to begin observation missions in support of Chinese ground forces. It later flew missions to resistance forces operating behind enemy lines in French Indochina. The squadron was redesignated the 19th Tactical Air Support Squadron, then organized in July 1963, activated as the 19th Observation Squadron on 5 Feb 1942. The squadron activated on 2 Mar 1942 at Miami Municipal Airport as part of the Air Force Combat Command, five days later, it moved to Jacksonville Municipal Airport, Florida. Two days after that, it part of Army Air Forces. On the 29th, it part of the 66th Observation Group. It moved to Pope Army Airfield, North Carolina on 11 May 1942, while there, it was redesignated as the 19th Observation Squadron. On 19 October 1942, it moved to Morris Field, North Carolina, on 2 April 1943, it changed name once again, to 19th Liaison Squadron. The following day, it transferred bases to Camp Campbell, Kentucky, on 22 June 1943, it changed airfields once more, to Aiken Army Airfield, South Carolina. On 11 August 1943, it was assigned to I Air Support Command and it flew anti-submarine missions using A-20 Havocs, B-25 Mitchells, and O-52 Owls, while undergoing observation training at these various bases in the southeastern states. They used L-1 Vigilants, L-2 Grasshoppers, Aeronca L-3s, L-4 Grasshoppers, L-5 Sentinels, L-6 Grasshoppers, p-39 Airacobras, P-43 Lancers, and P-51 Mustangs were also in the squadron aircraft inventory. From Aiken, the squadron shipped cross-country to Camp Anza, California and this was a transit base for the squadron, as it shipped out to Bombay, India. It arrived in India on 9 April, and was attached to U. S. Army Forces and it spent an itinerant few weeks further training in India, moving through Kanchrapara and Ondal, to land in Chabua on 17 May. It then moved onward to Kunming, China arriving on 29 May 1944 and they were attached to Y Force, to begin observation missions in support of Chinese Nationalist ground forces. They supported Y Force until 8 August and their American parent unit would be variously Fourteenth Air Force and the 69th Composite Wing. At various times, the 19th operated detachments from Kunming, Poashan, Wenshan, Yunnanyi, Chihkiang, Kweiyang and it moved bases to Chengkung on 28 March 1945. On 1 August, the 19th was placed under control of Tenth Air Force

20th Reconnaissance Squadron
–
The 20th Reconnaissance Squadron is a United States Air Force unit, based at Whiteman Air Force Base, Missouri. It currently flies the General Atomics MQ-1 Predator and is assigned to the 432d Wing at Creech Air Force Base, Nevada. It was originally activated as the 20th Transport Squadron in 1940 and served as a troop carrier unit in Panama during and after World War II, until it was inactivated in 1949. Activated in 1965 as the 20th Tactical Air Support Squadron, it served notably for seven and a years of combat duty during the Vietnam War. While in inactive status, the two squadrons were consolidated into a single unit, the 20th TASS was reactivated at Shaw Air Force Base in 1990, and again inactivated on 31 December 1991. The unit was redesignated as the 20th Reconnaissance Squadron and its reactivation at Whiteman took place on 14 January 2011, the 20th Transport Squadron was activated at France Field, Panama Canal Zone, on 15 December 1940, but had only one officer and no airplanes until February 1941. The squadron became operational by March 1941 when the Squadron obtained its first aircraft from France Fields 16th Air Base Squadron, with this solitary aircraft, the Squadron undertook daily flights to Albrook Field and, from there, on to Rio Hato Field and return. By May, the squadron began flying international flights, starting one to Managua, Nicaragua. By the time of the Pearl Harbor Attack on 7 December 1941, the squadron became the 20th Troop Carrier Squadron in July 1942 and flew many different types of aircraft, several being one of a kind. The Squadron moved from France Field to Howard Field on 19 February 1942, some aircraft were detached to Waller Field, Trinidad and Borinquen Field, Puerto Rico. Flight A left the squadron entirely on 22 December 1941 when it was detached to the 92d Air Base Group at Waller Field, the C-47s were followed on 19 June by two Consolidated OA-10 Catalina amphibians and a locally procured Stinson C-91. It also flew a single Junkers C-79 trimotor, which was given USAAF serial 42-52883, and a Hamilton UC-89 and these local acquisitions were a measure of the near desperate need for transport aircraft being felt by the squadron and Sixth Air Force at the time. In March 1943, a pilot was dispatched to Santiago, Chile, by early 1943, the unit had 30 officers and 234 enlisted. By June 1943, all had been reassigned out of the squadron, as Howard Field became more crowded with bomber units, the squadron moved in June 1943 to Albrook Field. The unit was redesignated as the 20th Troop Carrier Squadron on 13 November 1943, by November 1944, the unit had finally started benefiting from the production of transport types in the United States, and could finally approach some semblance of standardization in its fleet. The last year of the war, with the general wind-down of the size and breadth of Sixth Air Force, by this time, the Squadron had also received some Curtiss C-46 Commandos. Routine transport operations within Panama, South and Central America continued, after the end of the war, the squadron continued to provide transport for Caribbean Air Command, and was equipped with Douglas C-54 Skymasters in 1946. It was attached to the 314th Troop Carrier Group, which moved to Albrook in October 1946, in July 1948, its heavy transports deployed to Germany to assist with the Berlin Airlift

23d Flying Training Squadron
–
The 23d Flying Training Squadron is a unit of the United States Air Force, currently assigned to 58th Operations Group performing helicopter training at Fort Rucker, Alabama. Its mission is providing Air Force helicopter flight training for all undergraduate pilots proceeding to flying careers in the Air Force’s UH-1N Huey, USAF rotary wing students receive their wings when their Fort Rucker pilot training class is completed. The 23d’s lineage goes back to the 76th Bombardment Squadron which was designated on 20 November 1940 and activated on 15 January 1941. It was re-designated as the 23d Antisubmarine Squadron on 3 March 1943, coastal patrols were flown over the southeast coast looking for German U-Boats. Deployed to Batista Field, Cuba on 28 February 1943, where it conducted operations until 24 April, then moved to Edinburgh Field, from Trinidad, was moved to Zandrey Field, Surinam between 15 August 1943 and December. The unit also had elements at NAS Guantanamo Bay, Cuba, one flight of the squadron was temporarily stationed at Caracas Airport, Venezuela. With the Navy taking over the mission in mid-1943, the squadron returned to the United States via Borinquen Field, Puerto Rico. It was disbanded on 6 February 1944, the unit designation was reconstituted as the 23d Troop Carrier Squadron on 11 November 1944 at Baer Field, Indiana and equipped with C-47 Skytrains. Later operated from Advanced Landing Grounds in France, primarily resupply and casualty evacuation airfields, was upgraded to the C-46 Commando in early 1945. Inactivated on 7 September 1946 after serving with the United States Air Forces in Europe as a transport squadron supporting the occupation forces in Germany. The activation of the 23d Helicopter Squadron on 9 July 1956, was the result of the inactivation of the 516th Troop Carrier Group, the 516th had been a victim of an Air Force and Army dispute over control of assault helicopters. The 20 series Helicopter Squadrons were activated at Sewart AFB, Tennessee on 9 July 1956, assigned to 18th Air Force, the Squadrons were formed by absorbing the personnel, aircraft, and equipment of the 345th Troop Carrier Squadron. Assigned to Phalsbourg-Bourscheid Air Base France, the arrived at the new base between 7 and 15 November 1956, equipped with Piasecki H-21 Shawnee helicopters. Built for a fighter wing, Phalsbourg AB had plenty of hangar space. It could keep all its H-21Bs indoors, the 23d Helicopter Squadron provided very useful general airlift support throughout France. Standard helicopter missions included, Special Air Lift Mission, Administrative Support Mission, the H-21 was ideal for transferring injured U. S. personnel and dependents that required major medical attention to full-service hospitals from remote military sites across Europe. It was assigned to the 322d Air Division at Évreux-Fauville Air Base, France for operational control, mission scheduling, the 322d recommended that the 23d Helicopter Squadron be divided into four detachments for greater utilization. Detachments #1 and #4 remained at Phalsbourg with ten aircraft, major maintenance was performed by teams dispatched from Phalsbourg, and all H-21B-peculiar spare parts were stocked at Phalsbourg

23rd World Scout Jamboree
–
The 23rd World Scout Jamboree took place in Kirarahama, Yamaguchi in western Japan from 28 July to 8 August 2015. The event was attended by 33,628 Scouts and leaders, the theme was 和 Wa, A Spirit of Unity. The kanji 和, meaning harmony, unity or togetherness, was part of the theme, Wa is also an early name for Japan. The Jamboree site is a land with an area of 2.8 km north to south by 1 km east to west. There is a park on the site, where wildlife living on Kirarahama is preserved. Millions of wild birds visit Kirarahama every year, in addition, the site is equipped with water supply and sewage systems, as well as a sports dome and a swimming pool that were used for programs. Especially for the 23rd WSJ, two supermarkets, a hospital and an arena were temporarily erected, access to the site is easy by airplanes and Shinkansen bullet trains. The site is located 30 minutes from Shin-Yamaguchi Station on the JR Shinkansen line, four international airports serve within a 2-hour radius of the site, out of which Fukuoka International Airport and Kansai International Airport are located west and east of the site. Several inspections have been carried out on the Jamboree site by the Japanese government and other foreign governments, members from the World Organization of the Scout Movement also concluded that the site location is safe. At each World Scout Jamboree, a solidarity project is undertaken to support the attendance of Scouts from around the world who might not be able to attend the Jamboree for financial reasons and this Jamborees project was called Operation Kirara.
